Abstract
An induction furnace bottom blowing gas components erosion detection device is provided, which comprises a corrosion detection probe, a connection card, a transducer, and a computer processing instrument. The corrosion detection probes are arranged around a sensing hearth blowing air supply component, around 2 to 30 in total. The corrosion detection probe is composed of an electric thermo-couple, connected with the computer system through a connection card or a transducer, or directly linked with the computer processing system through the connection card, for detection corrosion speed and position of sensing hearth blowing air supply component. The detection device is suitable for positioning bottom blowing ejection gun under the condition of hearth oxygen blowing and melting equipment with bottom-blowing component. The application of the detection device can make people conveniently master corrosion speed and position of sensing hearth blowing air supply component, avoiding the damage of air supply component, and eliminating accidents of cylinder leakage.
Description
Technical field
The utility model relates to metallurgical equipment manufacturing technology field, particularly detection device of corrosion of induction furnace bottom aeration element.
Background technology
In order to satisfy the needs of production and scientific research, need bottom-blowing air feed element molten steel air feed in stove be installed at the furnace bottom of induction furnace and carry out the bottom blowing stirring, to satisfy the needs that molten steel stirred refining and decarburization.When induction furnace was installed bottom-blowing air feed element and blown in stove, particularly in stove during oxygen blast, because violent souring in high temperature, oxidation and the stove, the wear and tear speed of air supply device was difficult to grasp, and caused burning out of air supply device and caused the bleed-out accident.Because the special construction of induction furnace: capacity is less, and heat size is smaller, and furnace bottom is thinner, and eddy current is big, whether the air supply intensity in the stove is accurately required strict.Refining is different with general method, and air supply intensity can not be too big, otherwise will cause the interior molten steel material of stove to mix acutely, and splash strengthens, and the loss of steel increases, but also makes security incident easily; Air supply intensity again can not be too low, if air supply intensity is too low, stirring intensity is too little, does not reach the purpose of refining and decarburization, but also cause the air feed original paper to burn out easily, thereby often cause the generation of bleed-out accident.Still there is not to be applicable to well the device of corrosion of induction furnace bottom aeration element detection in the prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of detection device of corrosion of induction furnace bottom aeration element, is used to solve owing to the speed of deteriorating of air supply device at the bottom of the induction furnace is difficult to grasp, often causes air supply device to burn out to cause the technical barrier of bleed-out accident.
Detection device of corrosion of induction furnace bottom aeration element of the present utility model is provided with the detection probe of deteriorating around the induction furnace bottom air supply device, the quantity of the detection probe of deteriorating can be decided as required, can install 2~18 or more as 30, the detection probe of deteriorating is connected with transmitter by connecting plug-in unit, transmitter is connected with computer processing system, the detection probe of deteriorating sends the temperature signal of relevant position around the bottom-blowing air feed element that records to transmitter, the transmitter weak electric signal that detection probe records that will deteriorate is transformed into standard signal, again standard signal is sent to computing machine, computing machine is equipped with the software systems of handling this signal, can receive in real time, handle this signal, realize the deteriorate detection of the speed and the position of deteriorating of air supply device at the bottom of the induction furnace.
Around bottom-blowing air feed element, the detection probe of deteriorating is installed every certain gap length.When the nearest forward's probe of distance furnace bottom burns out, pick-up unit generation alerting signal, the position of deteriorating of reminding operator's spray gun this moment.The detection probe of respectively deteriorating sends its position temperature signal to transmitter and display device in real time, makes the operator grasp the temperature of spray gun each point and the position of deteriorating of spray gun at any time, guarantees not burn out the bleed-out accident that causes because of spray gun in the smelting process.The operator can in time regulate the size of refrigerating gas tolerance according to the speed of forward's idol temperature rise speed, the ratio that also can regulate oxygen and inert gas, thus assurance prolongs the serviceable life of spray gun, guarantees that again spray gun does not stop up simultaneously.
The detection probe of deteriorating is made of thermopair.Transmitter is transformed into standard signal with the weak electric signal that thermopair records, and sends computer processing system to.Computer processing system can adopt any system with A/D sampling function to constitute, and as Programmable Logic Controller (PLC), has the computer system of A/D capture card, has the intelligence instrument of A/D sampling etc.The detection probe of deteriorating thermopair also can directly insert the computer system of the A/D capture card with temperature sampling without transmitter.
Reach a certain section thermopair place when spray gun deteriorates, thermopair is blown, and the temperature of measurement is zero, but continues to deteriorate, and may make thermopair sintering again, again temperature value will be arranged.Detection device of corrosion of induction furnace bottom aeration element computer processing system of the present utility model has comprised the electric thermo-couple temperature pick-up unit, the alarm decision device, temperature indicating device, lever position indicator deteriorates, warning device deteriorates, the electric thermo-couple temperature pick-up unit detects each section electric thermo-couple temperature, show each section electric thermo-couple temperature sampled value by temperature indicating device, after thermopair blows, temperature value is zero, the alarm decision device is caught thermopair and is blown constantly, and report to the police by the warning device that deteriorates, cancel simultaneously the measuring ability of this section thermopair automatically, prevent to produce wrong report owing to sintering once more.The lever position indicator that deteriorates shows the position of deteriorating.
When being particularly suitable under the induction furnace bottom oxygen condition bottom blowing spray gun being installed, this pick-up unit uses, the smelting equipment that also can be used for other element with bottom-blowing, air supply device the deteriorate speed and the position of deteriorating can be conveniently grasped at the bottom of the induction furnace in its application, avoid air supply device to burn out, effectively the generation of breakout.
